Philo Judaeus De Ebrietate 177

[177] At all events I have before now often seen in the theatre, when I have been there, some persons influenced by a melody of those who were exhibiting on the stage, whether dramatists or musicians, as to be excited and to join in the music, uttering encomiums without intending it; and I have seen others at the same time so unmoved that you would think there was not the least difference between them and the inanimate seats on which they were sitting; and others again so disgusted that they have even gone away and quitted the spectacle, stopping their ears with their hands, lest some atom of a sound being left behind and still sounding in them should inflict annoyance on their morose and unpleasable souls.
